Hardware SD Card Issues

[TheCosmicWarrior]

Hi all, two days ago I installed custom firmware for this new 2DS I just got. Today I realized that none of my PC's are reading my microSD at all, but my console can detect the card just fine. Does anyone know what causes this issue and how to fix it?

Try to copy your contents through FTP or a data recovery software.

Once you have everything backed up, check if your SD card(s) are fake, faulty, or dying.

1. Copy everything off the SD card to a computer.
2. Quadruple reformat.
3. Full Write + Verify the empty card in H2testw. Do not skip.
